Used in microbiology laboratories to isolate and cultivate actinomycetes from soil, clinical, and environmental samples. Supports the growth of slow-growing filamentous bacteria, especially Streptomyces and related genera. Commonly used in antibiotic discovery programs, as actinomycetes are prolific producers of bioactive compounds, including many clinically used antibiotics. Also employed in agricultural research to identify strains that promote plant growth or suppress soil-borne pathogens. The medium can be modified with antibiotics or dyes to suppress unwanted microbial growth and enhance selective isolation.
